FRANCE mm TYPE SIPIINNING iirncnnvn Application filed August a, 1929, Serial No. 383,317, and; in rranc'enu ust 1d, 1928.

My invention relates "to improvements in the ring type spinning machine described and claimed in my co-pending application Serial No. 248,847, filed January 23, 1928.

One of the principal objects of the invention is to do away with the so-called tangent strands travelling froma point on the ring to the winding point on the bobbin and thus eliminate the force to which it is subjected in order to overcome the, inertia of the ring during the period of starting of the spindle as well as the force forovercoming the resistance offered by friction to which the ring is subjected during rotation. At the same time Iestablish a flexible sliding action during rotation of the said ring with respect to'the driving element thereof so that in connection with a braking arrangement I am enabled to adjust'the tensionof the thread. 1

My invention allows production of natural or artificialthread of the finest character, fiossy and of the least strength under very high spindle speeds, in continuousmachines of large production forsp inning, twisting and assembling. i

My invention will be more readily understood by those skilled in the art in the following description when taken in connection with the accompanying drawings inwhich Fig. l is a partial sectional view of the first embodiment of my invention; j

Fig. 2 is a plan view of Fig.1 looking from beneath with pulley removed"; j

.' Fig. 3 is a view similar to Fig. 1 of a secondembodiment of my invention I v Fig. 4 is a plan view looking from beneath in F ig. 3 with pulley removed;

Fig. 5 is a view similartoFigflof a third 7 1 embodiment of my invention; and

7 Referring to the drawingsmore in'deta-il and particularly to Figs. 1 and 2, therotatable ring is indicated by 1 which is' supported by means of a ball-bearing 2. Fixed to the ring 2 onthe lower edge thereof by means of a screw 2' is a spring 3 of suitable shape and adapted to bear constantly on the spindle 4, thus serving as a flexible driving connection between the ring 1 and the spindle 4 but ments 4 and 1 during braking of the ring as F ig."6 is asect-ion along the line" 6-6 of at the same time allowing any desired angular sliding displacement between the elements '1 and 4 if desired under braking action on the o ring 1 forwhich I provide a brake cord 3' of the usual type. In order to increase the adherence of the driving connection I may in certain cases niagnetize the spring 3 and I may also employ a plurality of springs 3. In any event I dispose a counter weight 5 on the ring 1 for. compensating for the weight of spring 8 which counter-weight is secured by means of a screw 5. The spindle 4 carries the usualdriving pulley 4".

' In the embodiment shown in Figs. 3 and 4, I secure a horseshoe magnet 6 to the lower side of the ring 1. Said magnet 6 preferably carries a flexible-arm? which is secured in place on the ring by means of a screw 7 and takes the place of the spring 3 in the first embodiment. 'The polesof magnet 6 straddle the spindle 4 and establish driving connection between the elements 4 and l by means of magnetic attraction but at the same time allows-a certain angular displacement between the elein the first embodiment. p I

I either construct the spindle 4 of a mag netic material or preferably cover the same with a coat of metalwhich is subject to magnetic attraction. Likewise I may employ'a plurality of mag nets 6 'instead'of'one as shown all secured in suitable fashion'to' the ring 1 As in the first embodiment a" counterweight 5'is provided for c'ompensating'for the weight of the magnet6." I

In certain cases I 'electro-magnets having the desired] shape may employ one of more and characteristics and I then vary the force of attraction by any suitable means known in the artfor altering the driving power.

Referring to- Figs; 5 and 6, rigidly secured a to the outside of thering 1 is a collar 8 pref- .erablyheld in place by means of threads;

The lower annular surface of said collar is completely finished and may be flat or other shape and horizontal'or of any inclination desired. A sleeve-'9 is adapted to rotate about the common symmetrical axis of the device,

with respect to the body 10 rigid with" spect to the sleeve 9 and is adapted to be Bat n -ie:

the plate 11 preferably through the medium of a ball bearing 12. Said sleeve 9 has rigidly inserted therein insuitable position a plu rality of driving rods 13. Conce-ntrically disposed on each of the rods 13 is a compression spring 14. Said springs function to forceannular ring lo ofssuitable dimensions against the finished surface ,ofic'ollar 8. Said ring 15 is concentrically disposed with refreely displaced in directions-parallel bathe axis of spindle d. The said ring 1 5 is provided with a plurality of holes 1'3 equal'in number to the rods 13 and through whichthe said rodsipass'freely.
